I recently upgraded a magento instance from 1.4.1 to 18.104.22.168, and after the updgrade was complete users can no longer use the one page checkout form to make purchases. At step #2, after filling out your billing info and clicking the “continue” button a JS alert appears and instructs the user to add data to all of the fields (see attached screenshot).
I am not seeing any JS errors in the console. My hunch is that the URL to which this AJAX request is being POST’ed too is not able to grab the values from the form fields. Any ideas as to why this is happening, and how I might go about fixing it?
